Final answer:
The idiomatic expressions 'have one's heart set on something' and 'set against something' reflect strong desires and dislikes, respectively, while expressions like 'know one's own mind' and 'narrow-minded' deal with the clarity of one's thinking and openness to new ideas.
Step-by-step explanation:
The expressions "have one's heart set on something" and "set against something" evoke the sentiment and determination associated with one's desires or dislikes. To have one's heart set on something suggests a deep and persistent desire to obtain or achieve a particular thing or goal.
Conversely, to be set against something implies a firm opposition or dislike towards a particular idea or course of action. These idiomatic expressions demonstrate the powerful role that emotions and personal resolve play in influencing our decisions and perspectives during our waking moments.
Expressions of the mind also carry significant weight in understanding human psychology and communication. When someone says they know their own mind, it indicates a clarity of thought and firmness in one's opinions or decisions. A mind bending concept, on the other hand, refers to an idea so complex or novel that it challenges one's understanding or perception. Being narrow-minded is often a criticism suggesting that a person has limited perspectives and is resistant to new ideas or change.
Understanding how these expressions reflect our mental states and interactions can provide insight into character motivations and narrative development in literary contexts, as evidenced by the provided textual examples.
